Abstract

2015 was named the International Year of Light and Light-based Technologies by the United Nations, initiated by different scientific societies in collaboration with UNESCO. This initiative shed light on the importance of light and light-based technologies and their positive effects on solving various challenges in such topics as agriculture, energy, education, and health.1 However, as “light scientists,” we have perfected our focus and practices to fulfill their potential. Photochemistry is a subspecialty of chemistry focusing on the chemical reactions which occur by the atoms’ light absorption. Different examples of photochemistry are vitamin D production with sunlight, photosynthesis, and vision initiation by rhodopsin. Photobiomodulation (PBM) is a mechanism in which a nonionizing visible or near-infrared light form is absorbed by endogenous chromophores causing photochemical and photophysical reactions on different levels of biological scales without causing any thermal damage. PBM therapy is a photon-based therapy based on the fundamentals of PBM. Various light sources such as lasers, broadband light, and light-emitting diodes (LEDs) in the near-infrared and visible spectrum can be used for this matter.2 © 2022, Journal of Lasers in Medical Sciences.All Rights Reserved.
